HAWKEYE AT HEART: Shonn Greene ran to MVP honors at last year's Outback Bowl, leading Iowa to a 31-10 victory over South Carolina.Reuters

When Kirk Ferentz saw Shonn Greene’s game-clinching, 53-yard TD run on TV last Sunday, it certainly brought back some good memories.

“Just looked like the same Shonn Greene that we were used to seeing here,” Greene’s old coach at Iowa told The Post last night.

Greene, the Jets’ most dynamic offensive player, might be the biggest star of the postseason so far. In two games, the rookie running back has rambled for 263 yards, which is the most in the NFL postseason so far and the second-most ever in the NFL for a rookie in his first two playoff games.

Greene two weeks ago rushed for 135 yards and a touchdown against the Bengals, then had 128 yards and a touchdown on Sunday in San Diego. Of the 53-yarder against the Chargers, Ferentz said, “It looked a little bit like a run he had in our bowl game a year ago.”

That was Greene’s last game as a Hawkeye, a 31-10 win over South Carolina in the Outback Bowl. And one question now is, how come he wasn’t drafted until the third round?

“I think, as I understand it, there are some teams that had concerns about him medically, which was a surprise to me,” Ferentz said. “I got a call from an NFL head coach the day before [the draft], where their medical team had told the coach they had some concerns about his medical status.”

Ferentz said he told that coach that Greene never missed a game during the season and didn’t skip any practices.

“We were surprised to hear there were any medical concerns at all,” Ferentz said.

Moreno, Wells and McCoy had promising rookie seasons. Brown only rushed for 281 yards for Indy. Granted, the Colts are a passing team, but Brown still only averaged 3.6 yards per carry.

Greene, meanwhile, ran for 540 yards, averaging five yards per carry. When he gets 10 carries or more, the Jets are 7-0, including the playoffs.

At Iowa, Ferentz insisted Greene wasn’t always dominant.

“It didn’t just happen for him. He really made his mark with us initially when he came here on special teams. He was unbelievable,” Ferentz said. “But when Shonn got his chance to really take over, which obviously he did a year ago, we all thought he would be a very good back.

“But for my money there wasn’t anyone in the country that was as consistently productive as Shonn was.”

Indeed, Greene ran for at least 100 yards in all 13 Iowa games in 2008. Ferentz also pointed out that “he really affected the demeanor of our entire football team.”

Ferentz used Greene’s TD jaunt against the Chargers, where he banged through a tackle, as an example and said, “That just creates a lot of energy with everybody on the football team.”
